Internet of things teaching and experiment system

Abstract

The invention discloses a teaching and experiment system of the Internet of things. The teaching and experiment system is composed of a teacher end (1), a gateway portion (2) and student ends (3), wherein the teacher end is composed of a teacher computer, a projector and a screen, the gateway portion mainly comprises a router supporting a wired multi-node WLAN and Wi-Fi, the router can be connected with the Internet, the student ends are composed of a plurality of student computers, student experiment devices and student personal smart phones or tablet personal computers, the student experiment devices, the student personal smart phones or the tablet personal computers and the wireless router form a wireless network, and each student experiment device comprises a single chip microcomputer used as the core portion, a plurality of LED indicator lamps, a Wi-Fi module, an E2PROM5, an RS232 serial port interface circuit, a sensor and a programmer, wherein the LED indicator lamps, the Wi-Fi module, the E2PROM5, the RS232 serial port interface circuit, the sensor and the programmer are connected with the single chip microcomputer, and RS232 serial ports are connected with the corresponding student computers. According to the teaching and experiment system of the Internet of things, the quality of scientific research teaching and experiment of the Internet of things can be improved, and the requirement for course teaching is met.

Description

technical field [0001] The invention belongs to the technical field of teaching and scientific research, and in particular relates to an Internet of Things teaching and experiment system used for teaching and scientific research of the Internet of Things. Background technique [0002] The Internet of Things is a network based on information carriers such as the Internet and traditional telecommunication networks that enables all ordinary physical objects that can be independently addressed to realize interconnection. The application of new technologies such as radio frequency identification technology, smart sensors, wireless networks, big data processing and cloud computing has greatly improved people's quality of life and intelligence. The Internet of Things is called the third wave of the development of the world's information industry after computers and the Internet. As a new industry growth point and a trend of future technological development, the Internet of Things h...

Problems solved by technology

However, the current Internet of Things teaching devices often have the following shortcomings: (1) wireless communication uses ready-made modules, and students' learning of the principles and functions of communication protocol stacks is only at the theoretical level, and the depth is not good; The existing wireless communication (such as Wi-Fi) functions, the experimental equipment is biased towards industrial applications or smart home applications, and the comprehensiveness is not good; (3) The experimental devices are independent, so that the laboratory equipment cannot be used as a unified system, poor connectivity
